During use, the passenger airbag is activated or deactivated by directly pressing knob 7 (which produces a high operating force to prevent accidental switch operation) until it reaches a certain stroke, then rotating the knob 7 (which produces a low rotational torque to improve operational convenience). Furthermore, the switch utilizes two operating mechanisms, allowing for independent adjustment of the pressing and rotating operating forces. This facilitates and versatility in adjusting subsequent force parameters, thereby reducing development costs.

[0036] As attached Figure 3 and attached Figure 5 As shown, the inner end of the cover 2 is also provided with an opening positioning groove 10.
